Start with one or two channels: Don't feel pressure to use every available channel. Focus on where your audience is most responsive.
Consider channel costs: Email is typically the most cost-effective, followed by SMS, then voice calls. Factor costs into your campaign budget.
Match channel to message type:
Email: Detailed content, product catalogs, long-form storytelling
SMS: Time-sensitive alerts, appointment reminders, short promotions
WhatsApp: Conversational engagement, customer service, rich media
Push notifications: Instant alerts, app-specific promotions
Voice calls: High-priority communications, personal touch for VIP customers
Test integrations before campaigns: Send test messages through each channel to verify everything works correctly before launching your campaign.
